PYSC 2010: Exam 2
1.What is the normal frequency range of human hearing?: 20 Hz - 20,000 Hz
2.What is the perceptual experience of a sound's frequency and amplitude?-
: high amplitude is loud sound, low amplitude is low sound, low frequency is low-
pitched sound, high frequency is high pitched sound
3.What are the steps involved in hearing?: 1.Sound wave causes eardrum to vibrate.
2. Vibration of the eardrum causes the ossicles in the inner ear to vibrate.
3. This causes the oval window to vibrate, creating a wave to move through the fluid in
the cochlea.
4. The wave moves through the basilar membrane as well.
5. Hair cells on top of the basilar membrane move up and down, causing the "hairs" (cilia)
to bend.
6. Bending of the hair cells releases neurotransmitter, which stimulates the auditory nerve.
4.What is the function of the semicircular canals?: sense orientation in space
5.difference between when a sound reaches one ear and when it reaches the other
ear: Interaural time difference
6.difference between the intensity of a sound at one ear and at the other ear:
Interaural intensity difference
7.Basilar membrane vibrates at a rate that matches sound frequency, Hair cells
generate action potentials at a rate that matches the sound frequency: - temporal
coding
8.what range of frequencies does temporal coding explain human hearing: -
less than 4,000 Hz
9.Wave in the cochlea causes a wave in the basilar membrane, Where the wave's
"peak" occurs depends on frequency: place coding

, PYSC 2010: Exam 2
10.what range of frequencies does place coding explain human hearing: -
greater than 4,000 Hz
11.where along the cochlea are high frequency and low frequency sounds
represented in place coding: high frequency near the base and low frequency near the
tip
12. What does it mean to say that taste is a chemical sense?: that it is a chemical
process
13.What are the five basic taste sensations?: Sweet, salty, bitter, sour, Umami
("savory")
14.What areas of the brain receive information about smell?: olfactory bulb,
prefrontal cortex, hippocampus, and amygdala
15.What types of receptors are found in the skin?: pain, temperature, and haptic
